DALANG UB982 Dual-Antenna High-Precision RTK Positioning Module

Dual-Antenna GNSS Engine Designed for High-Precision Heading
The DALANG UB982 module is an ultra-low-cost, low-power, high-performance Real-Time Kinematic (RTK) positioning module based on the UM982 chip, utilizing a full-system, full-frequency RTK engine. It integrates dual RTK engines and dual antenna inputs, providing not only real-time centimeter-level positioning accuracy but also achieving heading accuracy as high as 0.2 degrees with a 1m baseline. It is the ideal choice for applications requiring orientation such as UAVs, autonomous driving, and precision agriculture.

Dual Antennas & Dual Engines for Precise Heading and Stable Positioning
Leveraging its unique dual RTK engine and dual-antenna design, the UB982 can compute both position and heading simultaneously. Whether acting as a rover or a base station, this module provides reliable carrier attitude data alongside precise location information.

Designed for High-Performance Flight Control and Integration Applications
The UB982 module is fully compatible with open-source flight control systems like Pixhawk and APM, offering a variety of interfaces (UART, SPI, CAN). It is the perfect solution for advanced UAVs, robotics, and any high-precision navigation system requiring heading information.

Quad-Arm Helix Antenna for Enhanced Signal Reception
The integrated quad-arm helix antenna design is lightweight and high-gain, effectively enhancing signal reception capability and anti-interference performance, ensuring stable operation in complex environments.
